Homework Statement

Find the magnitude and direction for the vector A-B. Vector A=3m, Vector B=3m

Homework Equations

The Attempt at a Solution

Wouldn't it just be 0?
3-3=0

Thank you very much

It depends on the angle between them.

Thank you very much

If the only vectors are A=3.00m and B=3.00, vector -b would be -3.00, right? So wouldn't the distance be 0m? Or is this totally wrong?

Thank you

A vector has magnitude and direction, to talk about a vector of just 3m is meaningless.
If they were in the same line then A - B would be zero.
If they were at right angles the distance would be 4.2m
